Testing Resiliency


  • Tabletop exercises
    • involve teams discussing and working through hypothetical scenarios to assess their response plans and decision-making processes
    • help identify knowledge, communication, and coordination gaps
    • e.g., simulate a ransomware attack to test how well the organization’s IT and management teams collaborate to mitigate the threat and restore operations
  • Failover tests
    • intentionally causing the failure of a primary system or component to evaluate the automatic transfer of operations to a secondary, redundant system
  • Simulations
    • testing technique that replicates the conditions of a real-world disaster scenario or security incident
    • can reveal potential bottlenecks, inefficiencies, or vulnerabilities
    • e.g., cyberattack targeting the organization’s network infrastructure to evaluate the effectiveness of security measures and the ability to detect, contain, and remediate the threat
  • Parallel processing tests
    • Running primary and backup systems simultaneously to validate the functionality and performance of backup systems without disrupting normal operations
    • help ensure backup systems can handle the same workload as primary systems during an incident
